5-8 Tilt Measurement
The Tilt measurement helps to quickly measure the flatness of a CATV system and the gain of the splitters /
taps. This feature provides power levels for up to 16 channels. Upon entering the Tilt function, you will be
prompted to set the tilt channel plan. A minimum of 4 channels is required to begin measuring.
There are 2 markers in the tilt measurement screen. Press
Mark A
(F3) to activate MarkerA on the screen;
press F3 again to activate
Mark B
. You may only control the marker that’s currently active. When you move
the marker over a channel using the arrow keys, its level and channel type are displayed.
The Tilt measurement has two different view modes:
Graph
and
List
. Press F1 to toggle between them.

power.
